public class Field
extends java.lang.Object

Represents a Microsoft Word document field.

To learn more, visit the Working with Fields documentation article.

Remarks:

A field in a Word document is a complex structure consisting of multiple nodes that include field start, field code, field separator, field result and field end. Fields can be nested, contain rich content and span multiple paragraphs or sections in a document. The Field class is a "facade" object that provides properties and methods that allow to work with a field as a single object.

The getStart(), getSeparator() and getEnd() properties point to the field start, separator and end nodes of the field respectively.

The content between the field start and separator is the field code. The content between the field separator and field end is the field result. The field code typically consists of one or more Run objects that specify instructions. The processing application is expected to execute the field code to calculate the field result.

The process of calculating field results is called the field update. Aspose.Words can update field results of most of the field types in exactly the same way as Microsoft Word does it. Most notably, Aspose.Words can calculate results of even the most complex formula fields. To calculate the field result of a single field use the update() method. To update fields in the whole document use Document.updateFields().

You can get the plain text version of the field code using the getFieldCode(boolean) method. You can get and set the plain text version of the field result using the getResult() / setResult(java.lang.String) property. Both the field code and field result can contain complex content, such as nested fields, paragraphs, shapes, tables and in this case you might want to work with the field nodes directly if you need more control.

You do not create instances of the Field class directly. To create a new field use the DocumentBuilder.insertField(java.lang.String) method.

Examples:

Shows how to insert a field into a document using a field code.

 
 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 Field dateField = builder.insertField("DATE \\* MERGEFORMAT");

 Assert.assertEquals(FieldType.FIELD_DATE, dateField.getType());
 Assert.assertEquals("DATE \\* MERGEFORMAT", dateField.getFieldCode());

Method Detail

getFieldCode

public java.lang.String getFieldCode()

Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.

Examples:

Shows how to insert a field into a document using a field code.

 
 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 Field dateField = builder.insertField("DATE \\* MERGEFORMAT");

 Assert.assertEquals(FieldType.FIELD_DATE, dateField.getType());
 Assert.assertEquals("DATE \\* MERGEFORMAT", dateField.getFieldCode());
 
 

Shows how to get a field's field code.

 
 // Open a document which contains a MERGEFIELD inside an IF field.
 Document doc = new Document(getMyDir() + "Nested fields.docx");
 FieldIf fieldIf = (FieldIf) doc.getRange().getFields().get(0);

 // There are two ways of getting a field's field code:
 // 1 -  Omit its inner fields:
 Assert.assertEquals(" IF  > 0 \" (surplus of ) \" \"\" ", fieldIf.getFieldCode(false));

 // 2 -  Include its inner fields:
 Assert.assertEquals(" IF  MERGEFIELD NetIncome  > 0 \" (surplus of  MERGEFIELD  NetIncome \\f $ ) \" \"\" ",
         fieldIf.getFieldCode(true));

 // By default, the GetFieldCode method displays inner fields.
 Assert.assertEquals(fieldIf.getFieldCode(), fieldIf.getFieldCode(true));
 
 

getFieldCode

public java.lang.String getFieldCode(boolean includeChildFieldCodes)

Returns text between field start and field separator (or field end if there is no separator).

Examples:

Shows how to get a field's field code.

 
 // Open a document which contains a MERGEFIELD inside an IF field.
 Document doc = new Document(getMyDir() + "Nested fields.docx");
 FieldIf fieldIf = (FieldIf) doc.getRange().getFields().get(0);

 // There are two ways of getting a field's field code:
 // 1 -  Omit its inner fields:

 // By default, the GetFieldCode method displays inner fields.
 Assert.assertEquals(fieldIf.getFieldCode(), fieldIf.getFieldCode(true));
 
 

Parameters:

includeChildFieldCodes - true if child field codes should be included.

remove

public Node remove()
            throws java.lang.Exception

Removes the field from the document. Returns a node right after the field. If the field's end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns null.

Examples:

Shows how to remove fields from a field collection.

 
 Document doc = new Document();

 FieldCollection fields = doc.getRange().getFields();

 Assert.assertEquals(6, fields.getCount());

 // Below are four ways of removing fields from a field collection.
 // 1 -  Get a field to remove itself:
 fields.get(0).remove();
 Assert.assertEquals(5, fields.getCount());

 // 2 -  Get the collection to remove a field that we pass to its removal method:
 Field lastField = fields.get(3);
 fields.remove(lastField);
 Assert.assertEquals(4, fields.getCount());

 // 3 -  Remove a field from a collection at an index:
 fields.removeAt(2);
 Assert.assertEquals(3, fields.getCount());

 // 4 -  Remove all the fields from the collection at once:
 fields.clear();
 Assert.assertEquals(0, fields.getCount());
 
 

Shows how to process PRIVATE fields.

 
 public void fieldPrivate() throws Exception {

     // These fields are not a viable way of protecting sensitive information.
     // Unless backward compatibility with older versions of WordPerfect is essential,
     // we can safely remove these fields. We can do this using a DocumentVisiitor implementation.
     Assert.assertEquals(2, doc.getRange().getFields().getCount());

     FieldPrivateRemover remover = new FieldPrivateRemover();

     }

     doc = new Document(new ByteArrayInputStream(docStream.toByteArray()), loadOptions);

 doc.getFieldOptions().setFieldUpdateCultureSource(FieldUpdateCultureSource.FIELD_CODE);
 CultureInfo de = new CultureInfo("de-DE");
 field.setLocaleId(1031);
 field.update();
